Vines from Los Carneros are planted on low, rolling hills beneath Mount Veeder and the grapes, predominantly Pinot Noir and Chardonnay, enjoy a significantly cooler climate than their Napa neighbors thanks to regular fog and breezes from the nearby San Pablo Bay as well as the ocean. As the first AVA designated by climate, Los Carneros is notably warmer than the neighboring Sonoma Coast resulting in ripe, fruity harvests.
